Answer:

Both A and C can be given as correct answers.

Explanation:

Banner grabbing is an operation used by administrators of a network or hackers to gain access to a computer's informations remotely on the same network as the computer being used for this operation.

The two options "Telnet" and "Netcat" given in the question are protocols used by computers to read and write for other computers on the same network or a remote network and the options A and C are correct because they have the same address (168.15.22.4) and at the end of it they have the necessary port numbers specifying where to interact on the targeted computer.

I hope this answer helps.
